This isn't too important yet as I'm not close to using all my space, but others might be.
I was just checking out the usage in my gas gauge for the heck of it. I noticed that it seems to double count the space used. By this I mean under a main directory it gives a total of all files and sub-directories in it. Then it gives a total for each sub-directory. In the grand usage total it counts both numbers in the total.
For example, directory "A" gives a total of 112kb. With 2 sub-directories at 54kb each. 50kb for files and 4kb for each sub-directory. The gas gauge reads this as 220kb used. Shouldn't it actually read just 112kb used? If the main directory has the sub-directries in it's total, why is it adding the sub-directories again? Just curious.

If you're getting
If you're getting
54 KB /A/sub1
54 KB /A/sub2
220 KB /A
that would indicate that you have 108 KB of files in A, but not in a subdirectory.
For instance, near the top of your Gas Gauge page, you should have
100 KB /something/date/alpha
32 KB /something/date/beta
268 KB /something/date
112 KB /something/fish
128 KB /something/face
540 KB /something
(URLs were greatly munged, to protect your privacy, but you should be able to match up the numbers to see what I'm talking about.)
If you add the 100 and 32 for alpha and beta, that's 132, not 268. The difference comes from the files that are placed directly in the date directory. Add together the date, fish, and face directories and you get 508 KB, not 540 KB. The difference comes from the files that are in the something directory, not in a subdirectory.
If you add together all the numbers shown in somebody's Gas Gauge, you might get 34,912 KB, but at the bottom of the Gas Gauge page, it would shows a usage of 22,340 KB. At the same time, their file manager would show about 11,170 KB usage - half of what the Gas Gauge shows.
Perhaps that's where you got the idea that the Gas Gauge was adding things up twice. The problem arises from a move from one server to another that Craig made. He didn't realize that the block size had doubled, and that the file manager was showing usage as half of what it really was. I'm told that when he tried to fix it, users got really upset.
A secondary reason for introducing the Gas Gauge was to get people used to the notion that they are using and getting twice as much space as they thought. It's my intention, later this year, to fix the file manager so that it shows the correct amounts - and at the same time, to adjust everyone's space upward so that they continue to have as much available room as have been getting all along.
I don't like to see obscurantist sesquipedalianisms where simple words will do. It's not a matter of etymology but one of clarity.
